We're looking to reshape the homework we send home. At the moment, we use mathletics, expect 20 minutes of reading a day and send home weekly spellings. The reading and the spelling seems managable and appears to be making an impact (although we're always looking at better ways to set this) but we're currently not making the most out of maths homework. What do you all do and how do you know it has an impact on the children's learning (not just maths but all homework)? Do any of you use the pre and post teach model for homework?
